Description

Technical Field

[0001] This utility model relates to a stirring device, specifically a high-efficiency stirring device for waste PET fibers. Background Technology

[0002] PET contains polyethylene terephthalate, the most important type of thermoplastic polyester, commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. The processing of PET products generates a lot of waste PET fibers. To recycle these waste PET fibers, a waste PET fiber mixing device is needed.

[0003] Current waste PET fiber mixing devices typically only use mixing equipment to continuously mix the waste PET fibers. However, during the mixing process, the waste PET fibers easily adhere to the central shaft, and this part of the waste PET fibers is difficult for the mixing equipment to reach. Another part of the waste PET fibers accumulates at the edge of the mixing device cavity and cannot be mixed in time, thus leading to a decrease in mixing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency mixing device for waste PET fibers. By setting edge blades, when the edge blades are running at high speed, they can simultaneously mix the waste PET fibers and transfer them towards the central blade, thereby accelerating the mixing of waste PET fibers and improving the mixing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency stirring device for waste PET fibers, comprising a stirring tank and a first stirring mechanism disposed on the stirring tank. The stirring tank is a cavity structure with an opening on the upper end and a hollow interior. The first stirring mechanism includes a first motor, a central shaft connected to the output end of the first motor, and a plurality of central blades fixed on the central shaft. It also includes a rotating mechanism and a second stirring mechanism disposed on the rotating mechanism. The rotating mechanism includes a second motor, a lower edge shaft connected to the output end of the second motor, and a movable plate fixed below the lower edge shaft. The second stirring mechanism includes a third motor, an edge shaft connected to the output end of the third motor, and a plurality of edge blades fixed on the edge shaft. The edge shaft is rotatably connected to the lower part of the movable plate. The central blades and the edge blades are distributed in a crisscross pattern, so that the edge blades can extend between two adjacent central blades to fully stir the waste PET fibers between the two adjacent central blades, thereby achieving more efficient stirring.

[0006] Preferably, a discharge pipe is fixed to the lower end face of the mixing tank, and a valve is installed on the discharge pipe; the valve adopts a valve body that is already very mature in the existing technology, such as an electric valve.

[0007] Preferably, multiple support feet are fixed on the circumference of the lower end face of the mixing tank; the multiple support feet work together to keep the mixing tank and its structure stable.

[0008] Preferably, a crossbeam plate is also fixed on the mixing tank, and the first motor is fixed at the center of the upper surface of the crossbeam plate, with the central shaft rotatably connected to the lower surface of the crossbeam plate; this ensures that the structure of the first motor remains stable and the central shaft can operate stably.

[0009] Preferably, an inverted U-shaped upper support is also fixed on the mixing tank, and the second motor is fixed at the center of the upper end face of the upper support, with the lower shaft rotatably connected to the lower end face of the upper support; so that the structure of the second motor remains stable and the lower shaft can operate stably.

[0010] Preferably, the edge blades are designed to be angled, and the angle of the edge blades is 3° to 8°.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the first stirring mechanism, the rotating mechanism and the second stirring mechanism, enables the edge blades of the central blade to cooperate with each other, and the central blade and the edge blades are designed to cross each other, so as to carry out fine stirring of waste PET fibers, avoiding the phenomenon of insufficient stirring caused by them winding around the central shaft. Since the position of the edge blades is adjustable, the waste PET fibers located at the edge of the stirring tank can also be stirred in time, thereby improving the stirring efficiency. Since the edge blades are designed with an inclination, when the edge blades are running at high speed, they can stir the waste PET fibers at the same time and transfer the waste PET fibers to the location of the central blade, thereby accelerating the stirring of waste PET fibers.

[0020] Please see Figure 1The present invention provides an embodiment of a high-efficiency mixing device for waste PET fibers, comprising a mixing tank 1, a discharge pipe 2 fixed on the lower end face of the mixing tank 1, a valve 3 installed on the discharge pipe 2, the valve 3 adopting a valve body that is already very mature in the prior art, such as an electric valve, and multiple support feet 4 fixed on the circumference of the lower end face of the mixing tank 1. The multiple support feet 4 work together to keep the mixing tank 1 and its structure stable. The high-efficiency mixing device for waste PET fibers also includes a first mixing mechanism 5, a rotating mechanism 6 and a second mixing mechanism 7 disposed on the rotating mechanism 6, all disposed on the mixing tank 1.

[0021] Please see Figures 2 to 3 The mixing tank 1 is a cavity structure with an opening on the upper surface and a hollow interior. The first stirring mechanism 5 includes a first motor 52, a central shaft 53 connected to the output end of the first motor 52, and multiple central blades 54 fixed on the central shaft 53. A crossbeam plate 51 is also fixed on the mixing tank 1. The first motor 52 is fixed at the center of the upper surface of the crossbeam plate 51, and the central shaft 53 is rotatably connected to the lower surface of the crossbeam plate 51, so that the structure of the first motor 52 remains stable and the central shaft 53 can operate stably. The bottom is rotatably connected to the bottom support 55, which is fixed inside the mixing tank 1. The rotating mechanism 6 includes a second motor 62, a lower edge shaft 63 connected to the output end of the second motor 62, and a movable plate 64 fixed below the lower edge shaft 63. An inverted U-shaped upper bracket 61 is also fixed on the mixing tank 1. The second motor 62 is fixed at the center of the upper end face of the upper bracket 61, and the lower edge shaft 63 is rotatably connected to the lower end face of the upper bracket 61, so that the structure of the second motor 62 remains stable and the lower edge shaft 63 can operate stably.

[0022] Please see Figure 4 The second stirring mechanism 7 includes a third motor 71, an edge shaft 72 connected to the output end of the third motor 71, and multiple edge blades 73 fixed on the edge shaft 72. The edge blades 73 are designed to be inclined, and the inclination angle of the edge blades 73 is 3° to 8°. The edge shaft 72 is rotatably connected to the lower part of the movable plate 64. The center blades 54 and the edge blades 73 are distributed in a cross pattern, so that the edge blades 73 can extend between two adjacent center blades 54 to fully stir the waste PET fibers between the two adjacent center blades 54, thereby achieving more efficient stirring. In this embodiment, there are two sets of the second stirring mechanism 7, and the two sets of the second stirring mechanism 7 are symmetrical on both sides of the movable plate 64.

[0023] In this invention, waste PET fibers are first added to the cavity of the mixing tank 1. The first motor 52 is driven to run, causing multiple central blades 54 to rotate at high speed. At the same time, two third motors 71 are driven to run, causing two sets of edge blades 73 below them to rotate at high speed. Due to the cross-shaped design between the central blades 54 and the edge blades 73, they cooperate with each other to thoroughly stir the waste PET fibers between adjacent central shafts 53. Meanwhile, since the edge blades 73 are located at the edge of the cavity of the mixing tank 1, it is convenient to stir the waste PET fibers at the edge of the cavity of the mixing tank 1 in a timely manner. The second motor 62 can also be driven to run, causing the movable plate 64 to reciprocate within a certain angle range (within 75°), causing the two sets of edge blades 73 to continuously change positions, thereby touching the waste PET fibers at various positions in the cavity of the mixing tank 1. The inclined design of the edge blades 73 allows them to gradually transport the waste PET fibers towards the central blades 54 while stirring the waste PET fibers, thereby further improving the stirring efficiency. After stirring is completed, the valve 3 is opened and the discharge pipe 2 is opened to discharge the material.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
